YIELDING BEARING.

Original application led llebruary 21, 1912, Serial N o. 679,127. ,Divided and this application filed March 10, 1913. Seria1No.753,149.

To all whom 'it may concern i Be it known that we, JULIEN PEnsooNs and' ALPHONSE PEnsooNs, subjects of the Kingof Belgium, residing at Childoncl, nearLouvain, in the Kingdom ofBelgium, have invented certain new and useful Improvements in Yielding Bearings, of which the following is a specification.

This invention relates to a guiding device or yielding bearing for the shaft or spindle carrying the drum 1n centrifugal cream separa-tors of .that class in which is made'` use of a freely suspended drum such as de' scribed in our former Patent No. 946985 and in our pending application for a patent Serial No. 679127 filed Feb. 21, 1912, of which this application is a division.

One object of our invention is to provide an improved guiding device in which theresistance to the movements of the shaft or spindle from the center is increased automatically with the extent of the movements or oscillations of the shaft or spindle, said action being absolutely progressive while at the same time extremely reliable.

A further object lof ourl invention is to simplify the construction of such guiding devices.

With these objects in view, our invention essentially consists in the special arrangement and combination of parts as hereinappended claims.

after fully described and-pointed out in the Referring to the annexed drawing: Figure 1 is a vertical section of a centrifugal cream separator provided with a guiding device constructed according to our invention.` Fig. 2 is a horizontal section through the guiding device at an enlarged scale. F ig.,3 is a vertical section of the guiding device shown in Fig. y

The drum 1 of the cream separator is suspended as usual from the shaft or spindle 2 adapted to be rotated by a gearing 3. The construction of said gearing is well known and corresponds substantially to that shown and described in our former Patent N o. 946985. The shaft or rod 2 from which the i drum is suspendedv requires as usual to be guided below the ball bearing 9 for the hollow shaft 10 in which the said shaft'or rod 2 passes downwardly.

The guiding device is of the kind in which pins or pistons are pressed against the circumference of the shaft or rod 2 a-nd consists of four pins 5 pressing 'with their ends against the rod or spindle 2 and lodged in grooves of a cup member 7, the upper part of which forms a cup 8 supporting the cup containing the balls 9. The pins` 5. terminate near the outer periphery of Athe cupy `member 7 in conical surfaces 11 which are surrounded by four metal wires 12 wrapped about the cup member 7 (Fig. 2) and having their ends fixed to said cup member. The device thus formed is attached by a bolt (not shown) in the space 13 in the frame 14.- of the separator. It will be readily understood that owing to this arrangement the guiding device has a progressively increasing action. The oscillations ofthe shaft or rod 2 are transmitted to the pins 5 which tend to be displaced horizontally in the grooves of the cup member 7 in which they are lodged. Owing to the conical form of the external surface 11 of the pins 5, these latter begin to act on the lowest wireV 12 and, according as the amplitude of the swings of the shaft or rod 2 increases, the surfaces 11 successively act on two, three or four wires so that the resistance to the swings of the shaft or rod 2 appreciably increases with the amplitude lof the said swings.

In the lower part of the space 13 is screwed a metal plug piece 15 for insuring tightness at this part of the frame. The space 13 communicates through a hole 16 with the box 17 of the fra-me 18 containing the gear 3 so as to return thereto the lubricant which collects in the space 13 owing to the movement of the mechanism.

The described arrangement could evidently be reversed, that is to say the end surfaces 11 of the pins 5 could be in a vertical plane on the condition that the wires 12 be wrapped conically about the cup-member 7 or that the plane containing the wires be disposed at an angle with the plane of the en-dy surface 11 of the pins 5. The four wires 12 shown in Fig. 3 could also be replaced by a single wire suitably wrapped or coiled about the cup member 7 and the pins lcould be provided with semi-circular endsurfaces without modifying the action of the device. i What we claim is:

1. The combination with the shaft of a centrifugal cream separator of pins arranged radially around said shaft, a cup- Patented Aug. 18, 1914.

forming an angie with the end-surfaces ofsaid pins eoperating with said Wires.

2. The combination with the shaft of a Centrifugal 'Cream separator of pins urranged radially around said shaft, a oup` member in which said pins are guided hori- Zontally, Wires Wrapped about said oupmember and pressing` tbe pins against the shaft, and end-surfaces formed on the pins und eopereting with sii-id Wires whereby the number of Wires lpressing the pins against the shaft is inoreused'witb theA eX- 15 tent of the movement of the pins in the cup member.

n testimony whereof We have afxed our signatures in presence of two Witnesses.
